Maybe your .yarnrc is broken. Try to delete or recreate your .yarnrc.

I also face the similar problem. But in my case, problem is from my yarn.lock.

Hi @usama-asfar,

We fix this issue by cleaning the content of .yarnc and save it. and then try the execute you commands.

In my case, recreating .yarnrc or yarn.lock did not help, but upgrading from yarn 1.16.something to 1.17.3 fixed the issue for me.

I got this issue on my windows and I had a switch to ubuntu and yarn is working perfect, I hope those above fix will solve the problem,
Note: I don't switch to ubuntu not because of this :-)

I got the same issue on my windows i fixed this by clearing the .yarnrc file in "c:\user\admin".

[ndianabasi]

I solved mine by deleting the referenced.yarnrc file and running the command again.

[asadalibest1]

remove all data from .yarnrc and save it. [problem Solved]

I don't get how deleting .yarnrc is a solution when it's required in certain circumstances. Seems like all the solutions skirt around the actual problem.
